Abstract

Taking steps from Wilson’s distinction between strong and weak emergence, in this paper I cast doubts on the prospect of weak emergence. After discussing the relationship between properties set at different levels and supporting different counterfactuals and laws, I discuss one crucial condition for a property to be weakly emergent, one that is usually taken as the primary motivation for emergence, that of being “realization indifferent”. I set an argument aimed at showing that this realization indifference does not accord with systematic relations holding between properties set at the mental level vis-a-vis their realizers. Since it is not possible to have mental properties which are not systematic, mental properties cannot be weakly emergent properties.
